缝出口数据表以Excel格式

我尝试导出richdata表使用缝到Excel，并按照 http://docs.jboss.org/seam/2.1.0.GA/reference/en-US/html/excel.html#excel.intro缝出口数据表以Excel格式

它指示“要包含在应用程序中微软的Excel电子表格应用程序的支持，包括jboss-您的WEB-INF/lib目录中的seam-excel.jar以及jxl.jar JAR文件。“

我发现下面的两个依赖在线罐子..

战争的pom.xml

<dependency> 
    <groupId>org.jboss.seam</groupId> 
    <artifactId>jboss-seam-excel</artifactId> 
    <version>2.2.0.GA</version> 
</dependency> 
<dependency> 
    <groupId>net.sourceforge.jexcelapi</groupId> 
    <artifactId>jxl</artifactId> 
    <version>2.6.12</version> 
</dependency>

的web.xml

<servlet> 
     <servlet-name>Document Store Servlet</servlet-name> 
     <servlet-class>org.jboss.seam.document.DocumentStoreServlet</servlet-class> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>Document Store Servlet</servlet-name> 
     <url-pattern>*.xls</url-pattern> 
    </servlet-mapping> 

    <context-param> 
    <param-name>webAppRootKey</param-name> 
    <param-value>seam-excel</param-value> 
    </context-param>

的components.xml

<components 
     xmlns:excel="http://jboss.com/products/seam/excel" 
     xmlns:document="http://jboss.com/products/seam/document" 

     http://jboss.com/products/seam/excel http://jboss.com/products/seam/excel-2.1.xsd 
     http://jboss.com/products/seam/document http://jboss.com/products/seam/document-2.1.xsd"> 

     <excel:document-store use-extensions="true"/> 
     <document:document-store use-extensions="true"/> 
</components>

早些时候，我也被具有以下components.xml中

<excel:excelFactory> 
   <property name="implementations"> 
      <key>myExcelExporter</key> 
      <value>my.excel.exporter.ExcelExport</value> 
   </property> 
</excel:excelFactory>

这是导致部署的异常，也没有人在他们的代码中提到这个问题，我摆脱了这一点，并部署例外。

的jboss-缝Excel的2.1.2.jar和JXL-2.6.12.jar是在WEB-INF/lib目录

但部署，我没有找到.. org.jboss.seam.excel.DocumentStoreServlet任何地方，在的web.xml所以使用org.jboss.seam.document.DocumentStoreServlet

但是，我得到财产未发现异常就在登录的时候，下面是完整的错误堆栈跟踪.. loginAction.stationID无关与我的变更...

Deployment Exception : Could not create Component: org.jboss.seam.excel.excelFactory 
**Could not create Component: org.jboss.seam.excel.excelFactory**

PropertyNotFoundException在我添加seam excel依赖项时发生。

我的依赖关系树看到这个.. mvn dependency:tree，发现这个..

Excel的罐子自带的jboss-缝EJB和jboss-EL等。我认为org.jboss.el： jboss-el与我的项目中的一个已经碰撞..也.. .. jboss-seam：ejb：2.2.0.GA ..，试图把下面的排除在maven ..但dint工作要么..

，因为我以为，我不排除依赖正确，并与其他依赖相冲突。

这里是正确的版本...

<dependency> 
    <groupId>org.jboss.seam</groupId> 
    <artifactId>jboss-seam-excel</artifactId> 
    <version>2.2.0.GA</version> 
    <exclusions> 
     <exclusion> 
      <groupId>org.jboss.seam</groupId> 
      <artifactId>jboss-seam</artifactId> 
     </exclusion> 
     <exclusion> 
      <groupId>org.jboss.el</groupId> 
      <artifactId>jboss-el</artifactId> 
      </exclusion> 
    </exclusions> 
</dependency>

希望这有助于别人的未来。我必须说这个功能的记录很差，而且必须去几个论坛去了解究竟需要什么。我将停止使用POI方法导出excel :)。

你正在使用哪个JBoss版本？我假设的JBoss 5

入住此引用： https://community.jboss.org/thread/186791

这是一个较旧的版本，但也是有帮助的：

https://community.jboss.org/thread/184757

我剪切并粘贴下面的代码，因为我不目前无法访问代码，但如果不正确，它将很接近。 你需要在web.xml参考

<servlet-name>Document Store Servlet Excel</servlet-name> 
<servlet-class>org.jboss.seam.excel.DocumentStoreServlet</servlet-class> 


<servlet-mapping> 
<servlet-name>Document Store Servlet Excel</servlet-name> 
<url-pattern>*.xls</url-pattern> 
</servlet-mapping> 


<context-param> 
<param-name>webAppRootKey</param-name> 
<param-value>seam-excel</param-value> 
</context-param>

的jboss-web.xml中

<jboss-web> 
<class-loading java2ClassLoadingCompliance="false"> 
<loader-repository> 
seam.jboss.org:loader=seam-excel 
<loader-repository-config>java2ParentDelegation=false</loader-repository-config> 
</loader-repository> 
</class-loading> 
</jboss-web>

和components.xml中

<components xmlns:excel="http://jboss.com/products/seam/excel" 
xmlns:document="http://jboss.com/products/seam/document" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://jboss.com/products/seam/document http://jboss.com/products/seam/document-2.1.xsd 
http://jboss.com/products/seam/excel http://jboss.com/products/seam/excel-2.1.xsd"> 

<document:document-store use-extensions="true"></document:document-store> 

</components>

感谢您的评论gubuh，我已经按照前面那些链接的步骤。对web.xml，components.xml进行了更改，现在我还在WEB-INF下创建了新的jboss-web.xml（提及了更改），但问题仍然存在。我们使用Seam-2.2.0.GA和JBoss-5.1.0.GA。 – 2012-03-22 03:35:17

你可以发布更多的堆栈跟踪吗？ – gebuh 2012-03-22 13:40:22

我现在有一个不同的问题，添加了所有的细节。 – 2012-03-23 18:14:37
